public class ImagePortrayal3D
extends SimplePortrayal3D

Portrays objects as a thin flat rectangle displaying a provided Image. The rectangle can be oriented (always facing the user) or nonoriented (rotateable). If you don't understand this, you probably want oriented.

The image scaling is handled similar to how it's done in ImagePortrayal2D: the rectangle is scaled so that the smaller of the two dimensions (width, height) is equal to 1.0. The rectangle is then centered on its origin.

You can also specify whether or not the image is intended to be (semi-)transparent or fully opaque. If your image is fully opaque, you should DEFINITELY state this, because semitransparent images have some serious Java3D bugs. Specifically, semitransparent images may not be drawn in the correct order if they're piled up on top of one another. Thus a portrayal in the background may incorrectly appear in front of a portrayal in the foreground.

Objects portrayed by this portrayal are selectable.

getModel

public javax.media.j3d.TransformGroup getModel(java.lang.Object obj,
                                               javax.media.j3d.TransformGroup j3dModel)
Description copied from interface: Portrayal3D
Provides a TransformGroup which defines the node(s) to place in the scenegraph. This is the Portrayal3D equivalent of Portrayal2D's draw(object, graphics, drawinfo) method.

You should hang your model off of the TransformGroup provided. You should not transform that TransformGroup in any way -- it is used elsewhere. Instead if you wish to transform your model (rotate it etc.) you should add your own additional TransformGroup as necessary.

The provided TransformGroup can be null; in this case you need to create and return the outer TransformGroup for the object. If the provided TransformGroup is non-null, you should modify it and return the same.

SimplePortrayals should assume the following contract: at the point that getModel(...) is called, the parentPortrayal will have already been set if it exists, else it will be null.
